permutation

Merriam-Webster's Word of the Day for May 31, 2026 is: permutation • \per-myoo-TAY-shun\ • noun Permutation is a formal word for any one of the many different ways or forms in which something exists or can be arranged. It can also refer to a major or fundamental change in something based primarily on rearrangement of its existing elements. Permutation is usually used in its plural form. // Early permutations of the design look nothing like the final result. // The system has gone through several permutations . See the entry > Examples: “Megadeth have weathered nearly all of metal’s generational permutations , only once deviating from their ... formula with 1999’s infamously confused country’n’industrial mish-mash, Risk .” — Eli Enis, Pitchfork , 26 Jan. 2026 Did you know? “Ch-ch-changes!” David Bowie sang memorably in his classic (and appropriately titled) hit “Changes,” which concerns the phenomenon of artistic reinvention—something Bowie knew a lot about. In fact, he could have titled the song “Permutations,” though we admit that the word would have been a bit clunkier to sing. Permutation is, after all, all about change—specifically change (as in character or condition) of something based primarily on rearrangement of its existing elements. For example, Bowie’s artistic persona went through many permutations over the course of his career, from the alien rock star Ziggy Stardust to the aristocratic Thin White Duke, with the common denominator—the existing elements—being Bowie himself. ( Permutation can also be used for a form or variety resulting from such changes, and can thus refer to Bowie’s individual personae as well.) Permutation , perhaps ironically, has not changed all that much since it was borrowed into Middle English from Anglo-French as permutacioun .
